The roller is wound around and rotated synchronously with the axle. The roller has a wiping surface having longitudinally curved grooves, transversally curved grooves and wiping grains formed between the longitudinally and transversally curved grooves. The wiping grains are arranged in a curved matrix. Thus, the axle may be utilized to rotate the roller relatively to the panel to perform the rotating wiping and absorb the foreign object or debris to the longitudinally and transversally curved grooves of the roller, thereby preventing the surface of the panel from being scratched. Thus, the comprehensive wiping can be performed without forming any gap, thereby significantly enhancing the cleaning efficiency and quality and effectively enhancing the utility.

BACKGROUND OF THE INVENTION

(1) Field of the Invention

The invention relates to the technical field of cleaning a glass panel,and more particularly to a panel cleaning roller assembly with a goodcontact property for enhancing the cleaning effect of the panel cleaningroller assembly.

(2) Description of the Prior Art

Recently, due to the influences of the rapid development in the videoand touch technological fields, televisions, computer screens, tabletcomputers, smart mobile phones and various portable electronicapparatuses utilize liquid crystal displays or plasma displays as imageprocessing apparatuses. In order to enhance the human-oriented propertyand convenience in operation, a corresponding touch panel is installedonto the display. The liquid crystal display, plasma display or touchpanel utilizes a glass substrate as the main substrate. In order to makethe transmittance, electroconductivity and hardness of the glasssubstrate reach the required conditions and dimensions, the glasssubstrate is subjected to various processes, such as cutting, grinding,coating and the like. Before and after these processes, the surface ofthe glass panel needs to be cleaned to prevent the debris or foreignobject from scratching the surface of the glass panel and thus preventthe yield from decreasing.

The conventional cleaning apparatus has the scour cleaning tank and theultrasonic cleaning tank for performing the scour cleaning and theultrasonic cleaning, respectively. Thus, the cleaning device becomesenlarged and becomes the enlarging factor of the device occupying thearea. The above-mentioned cleaning device utilizes the independent tanksto perform the scour cleaning and ultrasonic cleaning, respectively.However, the cleaning device with the individual tanks for performingthe scour cleaning and the ultrasonic cleaning cannot completely removethe contamination. In addition, the device occupies the enlarged area,needs to be dried after cleaning, and cannot effectively overcome thefiber debris absorbing problem.

Thus, a dry cleaning roller is developed, in which a cleaning rollermainly serves as a main body. The rolling cleaning roller utilizes thegenerated electrostatic charges to absorb the debris and foreign object.However, the absorbed debris and foreign object cannot be discharged andare thus remained on the roller surface and tend to damage the panelsurface. Although grooves can be formed on the roller surface todischarge the debris and foreign object, the longitudinal grooves formgaps, which raise the problem of incomplete cleaning.

In other words, the conventional panel cleaning technologies havevarious problems and thus cannot possess the rapid and effectivecleaning effect, thereby affecting the panel cleaning efficiency andquality. Thus, the prior art needs to be improved to satisfy the actualrequirement in use.

SUMMARY OF THE INVENTION

It is therefore a main object of the invention to provide a panelcleaning roller assembly capable of performing the comprehensive panelwiping and thus discharging the debris and foreign object rapidly andeffectively, thereby significantly increasing the cleaning efficiencyand quality thereof.

The invention mainly achieves the above-identified object by providing apanel cleaning roller assembly having an axle serving as a rotating bodyand a roller serving as a wiping body. The roller is wound around androtated synchronously with the axle. The characteristic lies in that theroller has a wiping surface. The wiping surface has a plurality oflongitudinally curved grooves, a plurality of transversally curvedgrooves, and wiping grains formed between the longitudinally andtransversally curved grooves, which are cross-interleaving, so that thewiping grains on the wiping surface of the roller are arranged in acurved matrix.

According to the embodied implementation of the technological means, thecleaning roller of the invention utilizes the axle to rotate the rollerrelatively to the panel to perform the rotating wiping and generate theelectrostatic charges to absorb the foreign object or debris to thelongitudinally and transversally curved grooves of the roller, therebypreventing the surface of the panel from being scratched. The wipingsurface of the roller is formed with the wiping grains arranged in thecurved matrix, so the comprehensive wiping can be performed withoutforming any gap, thereby significantly enhancing the cleaning efficiencyand quality thereof and effectively enhancing the utility thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The invention provides a panel cleaning roller assembly with thedetailed structure shown in FIG. 1. The panel cleaning roller assemblyhas an axle (10) serving as a rotating body, and a roller (20) servingas a wiping body. Each of two ends of the axle (10) has a shaft (11) tobe connected to and thus rotated by a driving apparatus of a machine.Also, an edge of one of the ends of the axle (10) has a flange (12) withthe larger diameter to prevent the roller (20) from escaping.Furthermore, an edge of the other one of the ends of the axle (10) has astopper (15), which has the larger diameter and can be passed by theshaft (11). The stopper (15) is adhered to an end surface of the axle(10) to restrict the roller (20) from escaping. The above-mentioned axle(10) is the same as that of the existing art, is not the characteristicof the invention, and will not be described in detail.

The characteristic of the invention lies in that the roller (20) is madeof a plastic or rubber material and can generate electrostatic chargesafter rubbing, as shown in FIGS. 1 and 2. The roller (20) can be woundaround the axle (10) and rotated synchronously with the axle (10). Also,the roller (20) has a wiping surface (25) having a series oflongitudinally curved grooves (26), a series of transversally curvedgrooves (27) and wiping grains (28) formed between the longitudinallyand transversally curved grooves (26, 27), which are cross-interleaving,so that the rows and columns of wiping grains (28) on the wiping surface(25) of the roller (20) are arranged in a curved matrix without forminga fixed gap on the wiping surface (25) of the roller (20) so that thecomprehensive wiping can be obtained. Each of the longitudinally andtransversally curved grooves (26, 27) has a downward converging taperedsurface (260/270) to enlarge the deformation space above the wipinggrain (28) and to generate the better absorbing property to facilitatethe discharge of the debris and foreign object.

Thus, the roller (20) can be formed with the wiping grains (28) arrangedin a curved matrix using the longitudinally curved grooves (26) and thetransversally curved grooves (27) to construct a comprehensive panelcleaning roller assembly capable of wiping the panel and housing aforeign object.

When the panel cleaning roller assembly of the invention is usedpractically, as shown in FIGS. 2 and 3, the cleaning roller of theinvention utilizes the axle (10) to rotate the roller (20) relatively tothe panel (50) to wipe the panel (50). Because the roller (20) is madeof a plastic material, electrostatic charges are generated when theroller (20) is rotating and wiping, so that the foreign object or debrisis absorbed into the longitudinally and transversally curved grooves(26, 27) of the roller (20). It is possible to prevent the surface ofthe panel (50) from being scratched when the roller is rotating. Inaddition, the wiping surface (25) of the roller (20) is formed with thewiping grains (28) arranged in a curved matrix so that the comprehensivewiping can be performed and no gap is formed. Thus, the cleaningefficiency and quality of the invention are significantly increased, andthe utility of the invention is effectively enhanced, thereby increasingthe added value and the economic effectiveness of the invention.
